ABSTRACT
La arteritis actínica es la lesión producida a las arterias por la exposición a radiaciones ionizantes utilizadas previamente para el tratamiento radioterápico por diagnóstico de una neoplasia maligna y se presenta tras años de la exposición. Presentamos el caso de una paciente con antecedentes de Cáncer del canal anal con exposición a radioterapia en zona pélvica 21 años atrás que presento síntomas 8 años antes con signos de isquemia progresiva recibiendo tratamiento médico hasta llegar a isquemia critica en el miembro inferior izquierdo 7 meses antes con dolor en reposo y presentar lesión en hallux izquierdo 15 días antes de su internación, por lo que tras el fallo del tratamiento médico se optó por la revascularización con la realización de un By Pass extra anatómico.
Actinic arteritis is the lesion produced in the arteries by exposure to ionizing radiation previously used for radiotherapy treatment by diagnosis of a malignant neoplasm and occurs after years of exposure. We present the case of a patient with a history of anal canal cancer with exposure to pelvic radiotherapy 21 years ago who presented symptoms 8 years earlier with signs of progressive ischemia receiving medical treatment until critical ischemia in the left lower limb 7 months before With pain at rest and present lesion in the left hallux 15 days before their hospitalization, so that after the failure of the medical treatment was revascularization with the realization of an extra anatomical By Pass.

The aim of this article is to describe the clinical, pathophysiology and diagnostic imaging aspects of median arcuate ligament syndrome (MALS) by presenting clinical cases and literature review. Development: The median arcuate ligament syndrome corresponds to a clinical syndrome secondary to the extrinsic compression of the celiac trunk by fibrous bands of the median arcuate ligament. In recent decades, some authors have questioned its true meaning and existence given the reported cases of asymptomatic patients who presented extrinsic compression of the celiac trunk by MAL. However, the presence of intestinal angina symptoms and certain specific imaging findings leads to consider its differential diagnosis and directs toward the corresponding study. The diagnosis is made by using Doppler ultrasound, Multislice Computed Tomography (CT) Angiography and Magnetic Resonance Angiography (MRA), the Angiography-fluoroscopy being left out of the first-line study. In recent years use of MRA has increased due to the absence of ionizing radiation and the high efficiency in the diagnosis. Within its complications include acute mesenteric angina and pancreaticoduodenal artery aneurysms secondary to the extensive formation of adjacent collateral circulation. Surgical treatment has been the most effective, having a very low recurrence.
El objetivo de este artículo es describir la presentación clínica, fisiopatología y diagnóstico imagenológico del síndrome del ligamento arcuato medio (LAM), mediante la presentación de casos clínicos y revisión de la literatura. Desarrollo: El síndrome del ligamento arcuato medio corresponde a un síndrome clínico secundario a compresión extrínseca del tronco celíaco determinado por bandas fibróticas del ligamento arcuato medio. En las últimas décadas, algunos autores han puesto en tela de juicio su verdadero significado y existencia dado los casos reportados de pacientes asintomáticos que presentan compresión extrínseca del tronco celíaco por LAM. Sin embargo, la presencia de un cuadro de angina intestinal y ciertos hallazgos imagenológicos específicos, hacen considerar su diagnóstico diferencial y orientar el estudio correspondiente. El diagnóstico se realiza mediante el uso de Ecografía Doppler, Angiografía por Tomografía Computada Multicorte y Angioresonancia Magnética, quedando la Angiografía Fluoroscópica fuera del estudio de primera línea. En los últimos años se ha potenciado el uso de la Angioresonancia por la ausencia de radiación ionizante y la gran eficacia en el diagnóstico. Dentro de sus complicaciones se encuentran la angina mesentérica aguda y aneurismas de la arteria pancreático-duodenal secundarios a la extensa formación de circulación colateral adyacente. El tratamiento más efectivo ha sido el quirúrgico, existiendo una muy baja recidiva.

Homocysteine has emerged as a significant marker for occlusive vascular disease, but there has been some debate as to whether it is just an association (risk marker) or actually a causative factor (risk factor). To elucidate this, a retrospective statistical analysis was done of data generated in the course of our study on homocysteine and vascular disease. Homocysteine, lipid profile components and lipoprotein(a) were estimated in fasting blood samples drawn from 252 controls and 536 patients of occlusive vascular disease. The data were analyzed by SPSS version 17. Mean homocysteine levels were significantly higher (p<0.001) in all patients categories, as compared to controls. In fact, homocysteine level was the most significant biochemical risk factor for vascular disease. The odds ratios due to hyperhomocysteinemia varied from 3.170-4.153. When the cut-off was increased by 5 µmol/L, the odds ratio became almost three-fold. The prevalence of hyperhomocysteinemia increased by @20%, when the cut-off was reduced by 5 µmol/L. Statistical analysis of our data revealed that homocysteine conformed to Hill’s criteria of causation. Moreover, hyperhomocysteinemia was treatable by the administration of B-vitamins, even if the cause was genetic. Hence morbidity due to vascular disease could be reduced by identification and treatment of hyperhomocysteinemia.

Branch pulmonary artery obstruction is one of the prime reasons for re-operation in patients who have undergone repair for tetralogy of Fallot. Branch pulmonary artery obstruction may develop over a period of time due to dilation of right ventricular outflow tract or it may be caused by residual stenosis after inadequate repair. This may lead to differential lung perfusion causing morbidity. Intra-operative capnogram monitoring reveals ventilation−perfusion relationship. We report two cases where the capnogram helped the diagnosis and management of branch pulmonary artery obstruction. We found a redundant patch in the first and an extra length of the homograft in second case which led to the obstruction. However, but for the changes in the intraoperative capnogram, this condition may by far remain undiagnosed considering the fact that it does not produce hemodynamic changes but can lead to postoperative morbidity.

We report a case of ophthalmic artery obstruction combined with brain infarction following periocular autologous fat injection. The patient, a 44-year-old woman, visited our hospital for decreased visual acuity in her left eye and dysarthria one hour after receiving an autologous fat injection in the periocular area. Her best corrected visual acuity for the concerned eye was no light perception. Also, a relative afferent pupillary defect was detected in this eye. The left fundus exhibited widespread retinal whitening with visible emboli in several retinal arterioles. Diffusion-weighted magnetic resonance imaging of the brain showed a hyperintense lesion at the left insular cortex. Therefore, we diagnosed ophthalmic artery obstruction and left middle cerebral artery infarction due to fat emboli. The patient was managed with immediate ocular massage, carbon dioxide, and oxygen therapy. Following treatment, dysarthria improved considerably but there was no improvement in visual acuity.

CONTEXT: The aim of this paper was to report on the characteristics that aid in establishing the diagnosis of basilar artery occlusive disease (BAOD) among patients with hemiparesis and few or minor symptoms of vertebrobasilar disease. CASE REPORT: This report describes two cases in a public university hospital in São Paulo, Brazil. We present clinical and imaging findings from two patients with hemiparesis and severe BAOD, but without clinically relevant carotid artery disease (CAD). One patient presented transient ischemic attacks consisting of spells of right hemiparesis that became progressively more frequent, up to twice a week. The neurological examination revealed slight right hemiparesis and right homonymous hemianopsia. Magnetic resonance imaging (MRI) revealed pontine and occipital infarcts. Magnetic resonance angiography and digital subtraction angiography revealed severe basilar artery stenosis. The other patient presented sudden left-side hemiparesis and hypoesthesia. One year earlier, she had reported sudden onset of vertigo that, at that time, was attributed to peripheral vestibulopathy and was not further investigated. MRI showed a right-side pontine infarct and an old infarct in the right cerebellar hemisphere. Basilar artery occlusion was diagnosed. Both patients presented their symptoms while receiving aspirin, and became asymptomatic after treatment with warfarin. CONCLUSIONS: Misdiagnosing asymptomatic CAD as the cause of symptoms in BAOD can have disastrous consequences, such as unnecessary carotid endarterectomy and exposure to this surgical risk while failing to offer the best available treatment for BAOD. Clinical and imaging features provided important clues for diagnosis in the cases presented.
CONTEXTO: O objetivo deste artigo foi de relatar as características que auxiliam no estabelecimento do diagnóstico da doença oclusiva da artéria basilar (DOAB) em pacientes com hemiparesia e poucos sintomas, ou sintomas leves de doença vertebrobasilar. RELATO DE CASO: Descrição de dois casos em um hospital público universitário em São Paulo, Brasil. Apresentamos características clínicas e radiológicas de dois pacientes com hemiparesia e DOAB grave, na ausência de doença carotídea (DCA) relevante. Um paciente apresentou ataques isquêmicos transitórios consistindo de hemiparesia direita transitória, que se tornaram progressivamente mais frequentes, até duas vezes por semana. O exame neurológico revelou hemiparesia direita e hemianopsia homônima direita. A ressonância magnética (RM) revelou infartos pontinos e occipitais. As angiografias por ressonância magnética e por subtração digital revelaram estenose grave da artéria basilar. Outra paciente apresentou hemiparesia e hipoestesia de instalação súbita, à esquerda. Um ano antes, ela havia apresentado vertigem súbita, na ocasião atribuída a vestibulopatia periférica, não investigada em maior profundidade. A RM mostrou infarto pontino à direita e infarto antigo no hemisfério cerebelar direito. Foi diagnosticada oclusão da artéria basilar. Ambos os pacientes apresentaram os sintomas enquanto faziam tratamento com aspirina, e se tornaram assintomáticos após tratamento com warfarina. CONCLUSÕES: O diagnóstico errôneo de DCA como causa de sintomas na DOAB pode ter conseqüências desastrosas, como a endarterectomia carotídea desnecessária e a exposição a tal risco cirúrgico, ao invés de oferecimento do melhor tratamento disponível para a DOAB. Características clínicas e radiológicas forneceram pistas importantes para o diagnóstico nos casos apresentados.

Locked-in syndrome is characterized by upper motor neuron quadriplegia, paralysis of lower cranial nerves, bilateral horizontal gaze palsy and anarthria, with preserved consciousness. It is due to a ventral pontine lesion following a basilar artery occlusion. We report the first Indian case report of locked-in syndrome, a 10-year old girl in whom the syndome was preceded by a ‘herald hemiparesis’. Although the exact etiology for the basilar artery occlusion could not be determined, treatment with low molecular weight heparin and warfarin was followed by partial recovery.

PURPOSE: To report a case of bilateral ophthalmic artery occlusion in rhino-orbito-cerebral mucormycosis. METHODS: Reviewed clinical charts, photographs, and fluorescein angiography RESULTS: An 89-year-old man with poorly controlled diabetes developed sudden bilateral ptosis, complete ophthalmoplegia of the right eye, and superior rectus palsy of the left eye. Brain and orbit magnetic resonance imaging showed midbrain infarction and mild diffuse sinusitis. On the 2nd day of hospitalization, sudden visual loss and light reflex loss developed. There were retinal whitening, absence of retinal arterial filling, and a total lack of choroidal perfusion on fluorescein angiography of the right eye. The left eye showed a cherry red spot in the retina and the absence of retinal arterial filling and partial choroidal perfusion on fluorescein angiography. On rhinologic examination, mucormyosis was noticed. Despite treatment, visual acuity and light reflex did not recover and he died 4 days after admission. CONCLUSIONS: Bilateral ophthalmic artery occlusion can occur in rhino-orbital-cerebral mucormycosis.

Sudden sensorineural hearing loss and vertigo (SSNHLV) has multifactorial causes, of which viral, autoimmune and vascular insufficiency are the most common. The therapeutic management for SSNHLV includes antiviral drugs, corticosteroids, vasodilators, normovolemic hemodilution therapy and hyperbaric oxygen therapy. Vertebrobasilar occlusive disease and carotid occlusive disease are seldom related to SSNHLV. Discussions concerning SSNHLV caused by occlusive vascular disease are important and necessary for both neurologists and otolaryngologists, since their therapeutic management and prognosis are very different from other causes of hearing loss and vertigo. Here, we present our experience with three cases managed with interventional treatment and conduct a review and discussion on the relevant literature. We conclude that investigation of vertebrobasilar and carotid occlusive diseases is necessary in patients over 50 years of age who present SSNHLV, mild neurological symptoms and a history of arteriosclerosis, high blood pressure or thrombosis.
Surdez sensorioneural súbita e vertigem súbita (SSNVS) podem ter múltiplas causas, e a infecção virótica, a doença autoimune e a insuficiência vascular são as mais comuns. O tratamento da SSNVS inclui drogas antiviróticas, corticosteróides, vasodilatores, terapia de hemodiluição normovolêmica e terapia hiperbárica. Raramente são relacionadas como causa a doença vertebrobasilar oclusiva e a doença carotídea oclusiva. Discutir SSNVS é importante e necessário para neurologistas e otolaringologistas, uma vez que a terapia e o prognóstico são muito diferentes conforme a etiologia. Apresentamos nossa experiência com três casos em que foi administrado tratamento intervencional para SSNVS de causa oclusiva em grandes vasos e apresentamos uma revisão e discussão da literatura pertinente. Concluímos que a investigação de doenças oclusivas vertebrobasilar e carotídea é necessária em pacientes acima dos 50 anos de idade com SSNVS, sintomas neurológicos moderados e uma história de arteriosclerose, pressão alta ou trombose.

Antiphospholipid syndrome (APS) is primarily considered to be an autoimmune pathological condition that is also referred to as "Hughes syndrome". It is characterized by arterial and/or venous thrombosis and pregnancy pathologies in the presence of anticardiolipin antibodies and/or lupus anticoagulant. APS can occur either as a primary disease or secondary to a connective tissue disorder, most frequently systemic lupus erythematosus (SLE). Damage to the nervous system is one of the most prominent clinical constellations of sequelae in APS and includes (i) arterial/ venous thrombotic events, (ii) psychiatric features and (iii) other non- thrombotic neurological syndromes. In this overview we compare the most important vascular ischemic (occlusive) disturbances (VIOD) with neuro-psychiatric symptomatics, together with complete, updated classifications and hypotheses for the etio-pathogenesis of APS with underlying clinical and laboratory criteria for optimal diagnosis and disease management.

Peripheral vascular disease [PVD] is a condition characterized by atheroscerotic occlusive vascular disorder of tile lower extremities and functionally it is defined as arterial narrowing causing a mismatch between the oxygen supply and demand resulting in symptoms of claudication, exercise limitations or tissue loss. To observe the prevalence and presentation and to review tile noninvasive approaches for the evaluation and treatment of patients presenting with peripheral vascular diseases. Department of Surgery. Bahawal Victoria Hospital, Bahawalpur. Twenty patients were in included in this prospective randomized study during tile period from July 2003 to June 2005. The relative frequency of PVD at BVH Bahawalpur was 1.2%. The majority of patients [60%] were in the 4[th] decade of life and male [90%]. The smoking was exclusively the major predisposing risk factor [90%]. The common [90%] presentation of patients was intermittent claudication with 60%, gangrenous disease with an average duration of 4 years. The lower limbs were involved in 90% cases with 70% bilateral disease. Majority [90%] of the patients was diagnosed clinically and the objective severity of the disease was assessed with Doppler sonography in all the patients. The ABI was <0.5 in 85% cases. The duplex scanning was needed only in 10% patients. Smoking remains exclusively the only major risk factor. Much time and money can be saved by evaluating and treating these patients by noninvasive approaches but prevention is the best therapeutic strategy achieving by abstinence from the smoking
